Hierarchy of modes in an interacting system
O. Tsyplyatyev, A. J. Schofield, Y. Jin +7
Studying interacting fermions in 1D at high energy, we find a hierarchy in the spectral weights of the excitations theoretically and we observe evidence for second-level excitation…
Unconventional Metallicity and Giant Thermopower in a Strongly Interacting Two Dimensional Electron System
Vijay Narayan, Srijit Goswami, Michael Pepper +6
We present thermal and electrical transport measurements of low-density (10 m), mesoscopic two-dimensional electron systems (2DESs) in GaAs/AlGaAs heterostructures at…
Probing spin-charge separation in a Tomonaga-Luttinger liquid
Y. Jompol, C. J. B. Ford, J. P. Griffiths +6
In a one-dimensional (1D) system of interacting electrons, excitations of spin and charge travel at different speeds, according to the theory of a Tomonaga-Luttinger Liquid (TLL) a…
